Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction.

Does deionized water remove chlorine?

Cons of RO and DI Filtration

RO on its own, for instance, cannot remove chlorine from drinking water without the added help of a carbon filter. ... Similarly, DI is not designed to remove bacteria and particulates, and the process won't clean water of these contaminants without additional filters.

What does a deionization filter do?

Deionization (DI) filters exchange positive hydrogen and negative hydroxyl molecules for positive and negative contaminant molecules in water. DI filtering and other processes are sometimes referred to as "water polishing."
